1) The first law of thermodynamic is based on the thermal equilibrium principle. 2) The heat added at constant volume is greater than that at constant pressure. 3) The latent heat of vaporization of water at the critical point is 2500 kJ. 4) A polytropic process PV" = C having the value of index 'n' as (0.0) refers to isochoric. 5) The first law of thermodynamic is a mass balance law. 6) Heat engines can have a thermal efficiency of 100%. 7) The C.O.P of the heat pump (in winter) is less than one. 8) The steam cycle efficiency decreases as the boiler pressure increases. 9) The steam cycle efficiency increases as the condenser pressure increases. 10) The steam cycle efficiency increases as the turbine inlet temperature decreases. 1) The first law of thermodynamic is based on the thermal equilibrium principle. 2) The heat added at constant volume is greater than that at constant pressure. 3) The latent heat of vaporization of water at the critical point is 2500 kJ. 4) A polytropic process PV" = C having the value of index 'n' as (0.0) refers to isochoric. 5) The first law of thermodynamic is a mass balance law. 6) Heat engines can have a thermal efficiency of 100%. 7) The C.O.P of the heat pump (in winter) is less than one. 8) The steam cycle efficiency decreases as the boiler pressure increases. 9) The steam cycle efficiency increases as the condenser pressure increases. 10) The steam cycle efficiency increases as the turbine inlet temperature decreases.
